1 q aiml- 1- 9 Th s invention elate to a headgate and Water drop "attachment for an irrigation" ditch a d more particularly to a deyice yhich'rnay beeasily and quickly removed from a ditch and'transportedfor use in another location.

The p m r o je o e nvention is t e late an di ec the v u e nd aw o wa e through an irrigation ditch, and its diseharge fromahigher to aloyver level.

no er ob ect is t 'y fnt the 'ev ne Wate it m r d n the s'it fi h downw r om t e hea lea e t i e a ditch a a'ltwe level- A still further object is to facilitate the securing of the headgate in proper location in the bed Of an irrigation ditch.

The above and other objects may be attained by e o s e tiqn whi mbo i among its features a'headgate adapted to be introduced into an irrigation ditch; said headgate having a Water passage opening through its upper edge, agate "ladjustably mounted on the headgate for regulating the flow of ,vvater through the passage and a Water chute detachy p e t t e hea eate in t e down tr am side to prevent the water flowing through the gate from eroding the bed 'ofthe ditch onthe downstream side thereof in the immediate vicinity of the gate.

Other features include a plate having its bottom edge shaped to conform to the general contour of an irrigation ditch, said plate having a rectangular gateopening entering its upper edge midway between its ends, an angle bar secured to the upstream side of'the'plate adjacent each side edge of the gate opening, each angle bar Y extending beyond the bottom edge of the plate to forfn anchors adapted'to be driven'into the bed of an irrigation ditch, 'a" reinforoingangle bar attached to the downstream side of the plate adjacent its upper edge and extending across the gateopening in spaged parallel relation'swith the bottom edge thereof, "the fijahge of. said last named angle bar which lies perpendicula'rto the .plate' projecting toward the'downstream side of r mote f m he bottom o the trou h ai h qlss ter ng thegpe ihes the giefg 'ti l n le bar'tq c up th trough 9.

Riveted or other- Wise secured to the upper edge of the plate II and extending transversely across the upper end Of 6 p ning I2 is a reinforcing angle bar l5,

mpr esa llfthe one flange of which lies against the plate I! while the opposite flange projects perpendicularly from the plate in a direction opposite the flanges of the angle bars I4, and in a plane coincident with the upper edge of the plate II. It will thus be seen that the plate will be properly reinforced and held against deformation when in transit or use.

In order to facilitate the setting of the headgate in proper position within an irrigation ditch I provide driving caps designated generally I8. each of which comprises an L-shaped body I! carrying on one face a flange I8 which is adapted to rest on the upper edge of the angle bar I5 immediately adjacent the plate I I. Extending perpendicularly from the flange I8, midway between opposite ends and to a point coincident with the edge of the body II opposite the flange, is a web I9. As illustrated in the drawings the upper ends of the bars I4 project beyond the upper edge of the plate II and seated on the upper ends of the angle bars are the portions of the plates I'I opposite those carrying the webs I9, while the web I9 of each driving cap is seated on the perpendicular flange of the reinforcing angle bar I5. These driving caps are preferably welded in place as illustrated in the drawings so that in positioning the headgate in an irrigation ditch, blows directed onto the driving cap will be transmitted directly to the angle bars I4 in order to force the sharpened ends I 5 thereof into the bed of the ditch. Formed in the reinforcing bar in planes substantially aligning with the longitudinal axes of the angle bars I4 are openings 20 the purpose of which will be more fully hereinafter explained.

In order to direct the water flowing through the gate into the proper direction, and to prevent erosion of the bottom of the irrigation ditch on the downstream side of the gate I provide a water drop or chute designated generally 2| which comprises a bottom 22 carrying at opposite side edges perpendicular side walls 23, the longitudinal edges of which opposite those joining the bottom are rolled as at 24 to form stiffening reinforcements which will serve to hold the chute in proper position. As illustrated in Figure 1 the side walls 23 of the chute 2! are cut away or beveled as at 25 to engage against the downstream face of the plate I I so thatwater flowing through the headgate will be restrained from lateral discharge. An end wall 25 extends transversely across the end 7 of the chute 2| opposite the beveled ends 25, and

contained within the rolled edges 24 of the side 7 walls 23 are rods 2! which are provided, adjacent the beveled ends 25 of the side walls 23, with hooks '28 which as illustrated in Figure 5 are adapted to enter the openings 20 in the reinforcing angle bar I5 in order ,detachably to couple the chute to the gate..

In use it will be understood that the headgate I is transported to the point at which it is to be introduced into a ditch and the pointed ends I of the angle bars I 4 are seated against the bottom or bed of the ditch, after which the gate is driven into place by successive blows on the driving caps I5. When the gate has been properly seated in the ditch, the chute 2| is connected thereto by entering the hooks 28 into the openings so that water flowing through the opening I2 in the plate II will be directed downwardly into the bed of a ditch in a lower level. Owing to the fact that the water contacts the bottom 22 of the chute it will be evident that the bed of the lower ditch in the immediate vicinity of the headgate II] will be preserved, and no erosion thereof will occur. Likewise the upper edge of the end wall 26 of the chute 2| is disposed at the level of the bed of the ditch on the downstream side of the gate, so that the water discharged from the chute will have no tendency ,to erode the bed of the ditch into which the water is being discharged. In this way the relative positions of the beds of the upper and lower ditches may be preserved and the erosive action on the ditch beds, due to the and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

In an irrigation ditch headgate of the type which includes a plate having its bottom edge shaped to conform to the general contour of an irrigation ditch, said plate having a rectangular gate opening entering its upper'edge midway between its ends, a reinforcing angle bar attached to the downstream side of the plate adjacent its upper edge and extending across the gate opening in spaced parallel relation to the bottom edge thereof, the flange of said last named angle bar which lies perpendicular to the plate projecting toward the downstream side of the headgate and having a hook receiving opening extending therethrough adjacent each upper corner of the opening in the headgate, a water drop attachment for said headgate comprising a trough having parallel side walls, a hook at one end of each side wall of the trough for entering the openings in the reinforcing angle bar of the headgate and coupling the trough to the gate, an end wall closing the end of the trough remote from the headgate, said end wall being designed to extend downwardly into the bed of an irrigation ditch with its upper end lying substantially level with the bed of the ditch whereby water discharged from the trough will be delivered substantially parallel with the bed of the ditch.
